I'm an older tech worker (sounded weird when I just read it out :-p ) and I've found there are two gross classes of startups. The ones that have a fire fast mentality, burn workers to the ground, etc. mentality and others which take it like a marathon as opposed to a sprint. I wish we had names for these two kinds of startups because they would save everyone some time when it comes to figuring out who to work for. Both are good in certain situations and for certain clases of people IMHO.
